It isknown that the combination of the working-powerU with the depression aiid release ot' a type-key, K-,will throw the type K up against the ink-ing-ribbon Q, paper It, and platen C, and impress acharacter on the paper, and also work the combined vibratory ratchets "l T2, so as to hold the carriage B B2 Bft and paper and 'platen immovable while the type impresses the character, but move the whole a `type-space distance after the impression, and while type and key are going back vtoplace; but the operation and functions of these improvements are as follows:

First, the hinge-rail A5, in writing,4 guides the carriage BBl B",an d with itthe paperRand platen C, horizontallyin line over the types K, and allows it to he turned up and off from over to a vertical position'at any time to bring the writing before the eyes, or to give access to clean or adjust the types, or to adjust or .exchange the inking-ribbon Q. v

Second, the hinges B of the ratchetbar frame E, after a line is written, allow the ratchetbar l? to be moved up and o the combined ratch'ets T T, while the paper-carriage 15 B B3 is' drawn back to piace.

Third, the trip stop E, when near the end of the line, tripsaud vbrates the hammer E F, which strikes and rings l'lic'hclld'F.I -Thcvtrip-stop also, at the endlf. the line, strikes .presses .the platen-driving ratchet, C, `which turns the vplaten ratchet-wlwel C: anal platen Gand nieves the paper 1t a liuc-space distance. At the same timethe ratchet-lever depresses theratchet-har arm 1i and lifts thc"ratchctbar Eo the combi ned rat-chats T T2, and the guide-rack (Y, which is-adj ustable in thespri ngrack C, and which determines the distance olthe vibration of the'ratchet-lever, and thereby the distancewh ich the ratchet-wheel and platen will tornanti move the paper,thus-guides nr regulates the tine space movement.

Fifth, the pressure-roller D andcarryingbands D! press the paper R against the platen C,and thereby aid the accuracy and surety with which thc platen, in turning,- moves the paper.

Sixth7 the depressioni of the hand-lever Il afteraiine is written linwindsthc pulling-cord lil from the small shcave H", and turns thc cone pnlleyH and winds up the connectingcord H on the large sheave H*',and draws the paper carriage B B2 B hack to place; but theH r connecting-cord, being attached to the hind :end ot' the ratchet lever Cbcfore the carriage wheel L and drivingwheel pulley iii, and drives the transmitting,lr mechanism L M M* NSN* N, and moves the hiking-ribbon Q when the spring-wheel turns ,forward in writingjand the holding-ratchet L holds the loose ratchetvwheel and transmitting mechanism ahd inking ribbon immovable Ywhile the spring-wheel turns hack ward when the paper-carriage B B 'l B? is drawn back to placcafter a line is written.

Eighth, the rocking frame l 1"" l moves theinkiugribbon Qlaterally,as desired, whenever the ink is exhausted in one line-course, and, being adjustable in the guide-raek Papy the springratchet l", it thereby regulates or guides the line-course of theinking-rihbon.

The combined vhratory ratchcts T T, ab. tached to the upper rocking bar, S, arethe letter-space ratehets. The 'ratchet-wheel C on the end of the platen (J is the platen ratchetand vthe ratchet-wheclr U on the spring-wheel axle G' is thespring-whcel ratchetwlieel.

and platen of a typewriting machine, theconr bination of a horizontal bar attnchetland pivotcd so it may vibrate across in front of the key-levers with thc vibratory frame and letter-space ratchets of a typewriting machine,
